An object 2.00 mm tall is placed 20.0 cm to the left of a double convex lens with a focal length of 10.0 cm. A second lens, double concave, with a focal length of 10.0 cm is 5.00 cm to the right of the first lens. Draw image to solve.
a. How far from the second lens will the final image be formed?
b. Is the final image real or virtual?
c. What is the height go the final image?
d. Is the final image erect or inverted?
